Testing - System Operation Check
WARNING: This page is about a different car, the 1995 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES
in GENERAL INFORMATION before disconnecting battery.
NOTE:
For DRB usage, see ENTERING ON-BOARD DIAGNOSTICS
under DIAGNOSIS.
- Disconnect negative battery cable and tape cable end (unless previously disconnected). Connect DRB to ACM data link connector. ACM data link connector is located at lower right of steering column.
- Use latest version of proper DRB cartridge. Turn ignition on. Exit vehicle with DRB. After ensuring no one is inside vehicle, reconnect negative battery cable.
- Using DRB, read and record active fault codes. Read and record any stored fault codes. Erase stored fault codes if there are no active fault codes. If problem remains, fault codes will not erase. Turn ignition off.
- Turn ignition on again and observe AIR BAG warning light. AIR BAG warning light should come on for 6-8 seconds, then go out, indicating system is functioning properly. If AIR BAG warning light either fails to glow or comes on and stays on, a system malfunction exists. Perform self-diagnostics. See DIAGNOSIS .
